I would prefer to keep Waller and Carter rather than Aiken and Campanaro. It's about the upside, Waller could turn out to be an unstoppable redzone target and Carter is just as good in the slot if not better than Campanaro without the injuries. So I think our receivers should be SSS, Perriman, Brown, Waller and Carter and put Campanaro on the practice squad. This way we could keep all 4 of our TE's on the team.
